(trivial-gray-streams:stream-listen stream)

Function: This is used by LISTEN. It returns true or false. The default method uses STREAM-READ-CHAR-NO-HANG and STREAM-UNREAD-CHAR. Most streams should define their own method since it will usually be trivial and will always be more efficient than the default method.

(trivial-gray-streams:stream-terpri stream)

Function: Writes an end of line, as for TERPRI. Returns NIL. The default method does (STREAM-WRITE-CHAR stream #NEWLINE).
